Yeah, absolutely! If you wanted to check if or how something changes a sound - for example if a sampler or effect does something to the sound even with “neutral” settings, you could just take the original sound and a recording through the sampler or effect, place them on two different tracks so that they play at the same time and invert the phase on one of them. You´ll have to play them at the same level, that might require some tweaking, but when you get the level right, it would cancel everything that is same as in the original, leaving only the differences.
This works, because when the phase is flipped on one track, everyhing that is exactly the same goes in the opposite direction. Like in this picture, everything that goes up, goes down in the inverted version and if you think about how a speaker cone works, you can imagine that if the speaker cone wanted to move in one direction and in the opposite direction at the same time - it would not move at all resulting in silence at that moment.
I also found this depiction of masking. The quiter signal in the same frequency range gets masked (overpowered) by the louder signal. When you now take away that signal, your ears will have to re-adjust to what´s happening.
Haha, psychoacoustic phenomena can certainly feel pretty crazy^^
